摘要：
The conductivity of single-phase ceramic materials based on proton-conducting perovskite La0.9Sr0.1ScO3 - alpha containing from 0.3 to 47 at % Fe in the scandium sublattice has been studied. Synthesis has been performed by burning with ethylene glycol. Measurements have been carried out by the four-probe (500-900 degrees C) and impedance (100-500 degrees C) methods in oxidizing and reducing atmospheres, as well as at different pressures p(O2)(2.1 x 10(4)-10(-15) Pa) and p(H2O) (0.04-2.5 kPa). Substitution of scandium with iron significantly decreases the proton conductivity.
